Another new node: circle_circle

The circle_circle node finds the intersection points between two circles.

• If the circles overlap, it will return two points
• If the circles are tangent (touch in one spot), it will return one point
• No points will be returned if:
  • the circles do not overlap or touch
  • the circles coincide (or have centers less than .01 pixels apart)
  • either circle has a diameter less than .01

Thanks to Jared Updike for the algorithm: https://gist.github.com/jupdike/bfe5eb23d1c395d8a0a1a4ddd94882ac

Enjoy! Circle_circle will be included in the next release of the Cartan Node Library. Please comment and share things you make with this or issues you encounter.
